BRANNING-MACHINE Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed March 29. 1906. Serial No. 308,819.

To all whom it may concern:

Be it known that I, JAMES W. BRYSON, or New Castle, in the county ofLawrence and State of Pennsylvania, have invented a new and usefulBranning-Machine, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, in which Figure 1 is a sectional endelevation of my improved apparatus; Figs. 2 and 3 are end elevationsshowing opposite ends; and Fig. 4 is a side elevation, with partsremoved.

Hy invention relates to that class of branners or plate cleaningapparatus wherein the sheets or plates are fed upwardly through the branor cleaning material.

The object of the invention is to provide a cheap, simple and effectivefeeding mechanism which will introduce and start the plates upwardlythrough the branner without the use of skilled labor. 7

In the drawings, 2 represents a branner case, having stationaryend-plates 3, 3; the side plates 2 are preferably removable and are heldbetween guide-strips on the end-plates as shown in Fig. 1.

The bottom of the receptacle consists of curved plates 4, 4 with theirinner adjacent edges spaced apart and provided with angles 5, 5, whoseflanges project upwardly and inwardly toward each other. The angles arepreferably adjusted so as to allow passage of the plate up between themby leaving a narrow slot between their edges. Below the angles 5 aredriven feed-rollers 6, 6, preferably having separate adjustable rollerportions 7,

1, as shown in Fig. 4. Above the inlet slot are provided guide lingers8, 8 which lead to feed-rollers 9, S), above which the guide fingers 10,10 lead to the feed-out rollers 11, 11. The form of these rollers ispreferably as shown in Fig. 4. Above the rollers 11 is a deflector 12which curves the plate over so that it drops and slides down the chute13. Below the feed-in rollers G, 6, are stationary vertically extendingguides 14, against which the upper end of the sheet slides as it isforced up into the bite of the feedrolls.

The sheets to be cleaned are fed in upon the swinging rest bars 15,having the supporting ledges or hooks 16 at their lower ends. These restbars are secured to a transverse supporting-bar 17, which is pivoted atits ends and rests upon the adjustable blocks 18. These blocks, at eachend, are provided with screw-threaded holes engaged by screw-spindles19, having bevel gear connection 20 with the shaft 21, having anadjusting wheel 22 at each end. The blocks 18 are guided between theslotted standards 23; and by turning the hand-wheel the position of thebearings may be adjusted. A slotted lever 24 projects from the bar 17,its slot being engaged by a pin projecting from a vertical slide 25.'This slide moves through suitable 1 guides 26 and carries at its upperend an internal cam 27. The cam 27 is engaged by a crank-arm 28,projecting from driven shaft 29.

In the form shown, 30 is the main shaft receiving power through thepulley 31. At its opposite end shaft 30 is provided with a sprocketwheel 32 which receives a sprocket chain extending over the sprocketwheels 33, 34 and 35, as shown in Fig. 2, by the dia grammatic line.Each of the shafts 6, 36 and 37 is provided with a pinion inter-meshingwith a correspending pinion on the other shaft of each pair, thusdriving the feed-in rolls and the rolls 9 and 11. At the belt pulley endone of the shafts 6 is provided with a sprocket-wheel 38 from which achain extends over sprocket wheel 39 on the shaft 29.

The shafts of the heaters 40 which stir up the cleaning material areconnected by pinions 4], and one of these shafts is provided with asprocket wheel 42 having sprocket-chain connection with a sprocket wheel43 on the main shaft 30.

In using the apparatus the slide 25 reciprocates continuously andthereby tilts the rest-bars backwardly and forwardly. When the slide ismoved down the rest-bars assume the dotted line position shown in Fig.1; and the sheet is then inserted by the attendant. As the slide 25 thenrises the rest-bars will be tilted forwardly into position shown in fulllines in Fig. 1, thus throwing the upper end of the sheet over againstthe stationary guides 14. On the next lowering movement of the slide 25the rest-bars tilt back, thus raising their lower ends and forcing thesheet upwardly until its upper end is engaged by the feed-rolls 6. Theoperator then inserts the next sheet, the rest-bars are tilted forwardlyand the operations thus go on continuously. Each sheet is successivelyfed up through the bran between the feed-rolls and fingers and thendrops upon the chute.

The advantages of my invention result from the automatic feeding of thesheets upwardly through the bottom slot in the cleaning machine. Theoperator simply drops the sheets one after the other into the rest-barreceiver when in tilted-out position, and the machine then throws overthe sheet and feeds it upwardly. The apparatus is simple and not liableto get out of order; and may be cheaply made and installed.

Variations may be made in the form and arrangement of the cleaningmachine and the feed-mechanism without departing from my invention.

I claim 10 5 1. A sheet-cleaning machine having a lower entranceopening, vertically arranged guiding means below the said opening, andan oscillating feeding receptacle arranged to receive the sheets ininclined position and then tilt their upper edges against the guidingmeans, said feeder being also arranged to raise said sheet during itsbackward movement: substantially as described.

2. A sheet-cleaning machine, having a lower entrance opening, a pair offeed rollers below said opening, a guide device below the feed rollers,an oscillating feeder receptacle, having a portion adapted to tilt thesheet in onedirection of. its movement, and to raise the sheet to thebite of said rolls by its opposite movement, and means for actuating thereceptacle; substantially as described.

3. In a sheet-cleaning machine, an oscillating feeding receptacle,arranged to receive a sheet in inclined position and to tilt the sheetin one direction of its movement, and to raise the sheet during itsopposite movement, and means for actuating the receptacle; substantiallyas described.

4; In a sheet-cleaning machine, a pivoted feeding receptacle having asheet-support below its pivot, and means for oscillating saidreceptacle, substantially as described.

5. In a sheet-cleaning machine, a pivoted feeding receptacle, means foroscillating said receptacle, and means for adjusting the pivotal pointof said receptacle; substantially as described.

6. In a sheet-cleaning machine, a feeding receptacle, consisting of aplurality of pivoted rest-bars having sheet supports at their lowerportions below their pivots, and means for oscillating said bars inunison; substantially as described.

7. In a sheet-cleaning machine, a feeding receptacle, consisting of aplurality of rest-bars having sheet-supports at their lower ends, afulcrum bar connecting the rest-bars above their sheet-supports, andvertically adjustable bearings for the fulcrum bar; substantially asdescribed.

8. In a sheet-feeding machine, having a lower feed-in opening, avertical sheet guide below the said opening, and a tilting feederreceptacle arranged to first tilt the upper edge of a sheet against thesaid guide and subsequently to raise the sheet; substantially asdescribed.

In testimony whereof, I have hereunto set my hand.
